GENERAL SUBJECT AREA

Assessment and Life Cycle Analysis of

Bioethanol as Source of Hydrogen

SPECIFIC TOPIC

Bioethanol from Water Hyacinth as source

of Hydrogen by Transient Conversion



4/18

INTRODUCTIONUtilization of renewable energy sources such as

aquatic biomass, considered as a waterways pest,

offers environmental benefits in the long term while

providing a new source of energy option to an

industry dependent on fossil and food grade fuels.

The main source of ethanol are sugar and corn with

sorghum in the interim which competes with the

food chain resources, thereby affecting food supply

and prices.

Low value crops such as wild grass (talahib) and

aquatic plants such as water hyacinth can be an

alternative source of ethanol feedstock that has poor

food value.4RM 513 TOPIC PRESENTATION by MRFSC

Hydrogen as fuel derived from biomass is still in

the introductory phase as far as the Philippine energy

sector is concerned, being in the tail end of theresearch paradigm due to financial constraints and

political priorities.

Hydrogen is highly flammable and must be stored

under great pressure and fuel cells as medium to

convert for practical use are but one of the

constraints since a requisite of fuel cell technology is

to have an industry that can locally develop the

architecture needed for the structure undertaking to

succeed in harnessing this type of green energy

source.

BACKGROUND OF THE STUDYWater hyacinth (Eichhornia crassipes) is a fast

growing perennial plant widely distributed especially

in the tropical regions and can cause infestations over

large areas of water resources that lead to a series of

problems that has been counteracted by using the

water hyacinths potentials in a variety of applications

such as in paper production and crafts and lately in

the extraction of ethanol. On the other hand, the

main problem of hydrogen, that can be made from

biomass gasification or natural gas, is storage due to

its flammability. Ethanol from water hyacinth can be

an alternative hydrogen storage medium due to its

molecularly bonded hydrogen and steam reforming to

release the hydrogen for use by the fuel cell. 6RM 513 TOPIC PRESENTATION by MRFSC

GENERAL OBJECTIVE

This research study aims to assess thecapability of ethanol from water hyacinth to be

the storage medium of hydrogen aside from

producing hydrogen without the use of

gasification methods.

SCOPE and LIMITATIONSThe study will use secondary data and

extraction methods of ethanol from waterhyacinth and design and simulation on the

reaction between hydrogen and ethanol and for

the combinations fuel cell architecture.

GENERAL SUBJECT AREAEvaluation and Resource Assessment of Off-shore

Wind Energy Combined with Ocean Thermal

Conversion System

SPECIFIC TOPICDesign of off-shore wind energy system for the

Philippine setting and combining with an ocean

thermal conversion mechanism to maximize output



11/18

INTRODUCTIONThe power system integration of off shore wind

power is challenged by its variability and limited

predictability and combining an ocean thermal

conversion system to offset these characteristics is

the subject of this research study that aims to

maximize the potential of this area of renewable

energy source. At present, the Philippines has an

onshore wind energy facility and as such could

createthe necessary onshore and offshore

infrastructure should be considered for the purpose

of increasing renewable energy sources, reducing

carbon emissions and improving the

interconnection capability of the power grid.. 11RM 513 TOPIC PRESENTATION by MRFSC

GENERAL OBJECTIVETo evaluate data gathered on the feasibility of

combining an off shore wind power generating facility

and an ocean thermal energy conversion system.

SCOPE and LIMITATIONSThe study will use data gathered about off shorewind and ocean thermal energy systems that will

include the latest technology and the applicability to

the Philippine setting. The proposed design andsimulation of an offshore wind power system will be

based on the selected site or local area.
